APPARATUS FOR PRESERVING EGGS.

Specification of Letters Patent.

Patented Jan. 14, 1908.

Application filed May 16.1907. Serial 150.374.004.

his invention relates to an apparatus forv sterilizing eggs, whichdepends or its operation upon the destroying of the germs in the eggs,the elimination of the fluid contained between the egg shell and liningtissue, and the a plication of .a suitable preservative Where y the eggscan be he t for an indefinite time without becoming sta e or decomposed.

The invention hasfor one. of its objects to improve and simplify theconstruction and operationof devices of this character so as to becomparatively easy and inexpensive to manufacture, readily operated, andthoroughly efficient and reliable in service.

A further object of the invention is the provision of an air-tightreceptacle for receiving the eggs which is connected with a vacuum pumpand provided with a steam jacket whereby the eggs can be first broughtto the desired temperature to kill the germs and open the pores of theshells and then subjected to the influence of a vacuum for eliminatingthe fluid containedbetween the egg shells and tissue, there beingprovision for supplyin a preservative solution to the receptacle orimpregnating the egg shell after the pores have been opened and thefluid extracted from the eggs.

A further object is the employment of a receptacle of the characterreferred to having separate controllable means for supplying suitablesolutions to the vessel for treating the eggs, one solution to act-as apreservative and the other to seal the pores of the egg shells.

With these-objects in view and others, as will appear as the descriptionproceeds, the invention comprises the various novel features ofconstruction and arrangement of parts which will be more fully describedhereinafter and set forth with particularity in the claims appendedhereto. I

In the accompanying drawing, which illustrates one of the embodiments ofthe invention, Figure 1 is a central vertical section of the sterilizingdevice with the attached parts shown in elevation. Fig. 2 is a plan viewof thevessel or receptacle. Fig. 3 is a frag mentary plan view of one ofthe egg trays or holders. v

Similar reference characters areemployed to designate correspondingparts throughout the several views.

Referring to the drawing, A designates the body of the device whichcomprises a vessel or receptacle 1 of any suitable size and.

shape and preferably of iron, and 2, a jacket surrounding the vesseland: cod crating therewith to form a steamspace 3, t e vesse being openat its top and provided with an annular flan e 4 that fits over thetopof the jacket or sheIl 2 and is bolted thereto so as to form asteam-tight chamber. The top of the vessel is closed by a removablecover 5 in the form of a disk or late having radial ribs 6. The cover.is he d in place by an arched cross-bar 7 terminating in hooks 8. thatengage around lugs 9-011 the outside jacket or shell, there bemg a screw10 at the center of the cross-bar which bears at its lower end a ainstthe cover'and is provided with a whee 11 permitting the screw to beturned to tighten or'loosen the cover by means of the cross-bar.

Arranged within the receptacle 1 are superimp'osed e g trays or holders12 in the orm of disks aving apertures 13 for the recegtionof the eggs,each aperture being provi ed with lugs 14, as shown in Fig.- 3, so thataround each egg will be aspace through which the preserving and seallnsolutions can freely pass. The traysor Iiolders 12 .are provided withlegs 15, the legs of. the

lowermost tray resting on the bottom of' the vessel 1, while those ofthe other legs rest directly on the trays themselves, whereby the traysare conveniently removable forthe purpose of placing the eggs to besterilized, and removing those that have been treated. The chamber .3 issupplied with: steam through'a'pipew that has a cut-off valve 17, an thesteam surrounds the vessel 1 so that heat is conveyed to the eggs forthe purpose of killing the germs therein and opening the pores of theshells.

In order to accurately determine the temperature to. which the eg s areraised, the

thermometer '18 is app'lie to the vessel, as

shown. Communicating with the egg-containing vessel 1 is a pipe '19connected with a vacuum pump and provided with a valve 20 Y cut-offvalves 28 and 29.

ing rovided in the pipe a vacuum gage 21.

.In t e cover 6 are apertured bosses 22 that receive the ends of adistributi pipe 23 provided with perforations or o t er outlet means.The pipe 23 has connected at opposite ends tanks 24 and 25 by flexibleconnections 26 and 27, and in the connections are In practice, the eggs,are laced in the holders 12 'and'the latter posltioned in the vessel 1through the to thereof and arranged in superimposedre ation. The cover 6is then clamped in osition so as to make an air-tight joint. e valve 17is opened to admit steam to thechamber 3 for the purpose of heating theeg s to the required temperature for killing t e erms and opening thepores of the shells, w 'ch temperature is ascertained. by thethermometer 18. The vacuum ump is then brought into'operation so t atthe section produced thereby. will draw the fluid contalned'between theegg shells and tissue through the ores of the s ell. After thisextraction of t efluid has been completed, the valve 20 is closed and lan antiseptic liquid, preferably a strong the uid that has latter.

pump is kept in operation so as to d sealingsolution, is applied to thevessel 1 by 0 ening the valve 28. This solution enters t e ores of the eg and takes the place of ieen abstracted from the Thus, superfluousantiseptic liquid is drawn-off through the drain cook 29, and after thevessel is drained, the cook 30 is closed and the valve 20 opened so thatthe air will a ain be umped out. The'steam supply, w 'ch has een cut offpreviously to the su ply of the antiseptic liquid, is again opene so asto heat the eggs and open the pores, thereby preparin the eggs for therece tion of the sealing so ution, which is sup phed by opening thevalve 29.-' This solution completel covers the eggs and fills the poresof the shells so that air will be prevented -fro-m acti on the eggs andcausing them to spoil, an simultaneously with the supply of the sealingsolution, the vacuullln t e eggs. and "render. them fit for immediate Pki -Fror'n'the foregoing description, ta-ken.in
